Former vice presidential nominee Sarah Palin’s son, Track, was arrested Saturday night after he allegedly beat his father at his parents’ home, according to court documents obtained by the Los Angeles Times.

The confrontation started when Track Palin, 28, allegedly said he was coming over to the Palin residence in Wasilla, Alaska, to pick up a truck.

His father, Todd Palin, told him to stay away because Track Palin had been drinking and taking pain medication, the newspaper reported. However, Track Palin showed up anyway.

When he arrived, Todd Palin allegedly confronted Track Palin at the front door with a pistol. Track Palin then broke a window, entered the house and began beating his father, the newspaper reported.

Sarah Palin called police at about 8:30 p.m. local time. When authorities arrived, Todd Palin and Sarah Palin were driving away in separate cars, with Todd Palin bleeding from his face.

Police spoke with Track Palin, who told them he had asked his father to shoot him several times before entering the house, according to the Los Angeles Times.

Track Palin is charged with first-degree burglary, fourth-degree assault and criminal mischief.

He was also arrested in January 2016 on domestic violence and weapons charges after allegedly hitting his girlfriend.

At the time of the 2016 arrest, Sarah Palin faced backlash for tying her son’s charges to then-President Obama’s treatment of veterans, accusing Obama of not providing proper care for veterans.
